AI Technical Summary

Technical Problem

In existing technologies, horizontal internal supports are difficult to install precisely during foundation pit construction, resulting in uneven distribution of support force and affecting the support effect of the support structure.

Method used

Auxiliary tooling, including walers, load-bearing components, and support components, is used. By hooking and erecting the load-bearing components on the walers, an installation foundation is provided, ensuring that the support components are in the preset position. The internal support is directly erected on the support components, achieving precise installation.

Benefits of technology

Ensure the accuracy of the internal support installation position to ensure uniform distribution of support force and avoid affecting the support effect of the support structure on the foundation pit.

Abstract

This utility model belongs to the field of building construction technology and discloses an auxiliary tooling for installing internal supports in foundation pits, including a waler, load-bearing components, and support assemblies. The waler is installed on sheet piles within the foundation pit. Multiple load-bearing components are provided, each including a hook portion, an attachment portion, and a bearing portion connected in sequence. The hook portions of the multiple load-bearing components are hooked at intervals to the upper end of the waler along its extension direction; the attachment portions extend vertically and abut against the side wall of the waler; and the bearing portions extend horizontally. Multiple support assemblies are provided, with both ends of any support assembly resting on the bearing portions of any two adjacent load-bearing components. The support assembly is used to support the internal supports. This auxiliary tooling for installing internal supports in foundation pits can ensure the accuracy of the internal support installation position, resulting in a uniform distribution of the support force provided by the internal supports and avoiding any impact on the support effect of the support structure on the foundation pit.
